Abstract: Today the protection of ecosystem has become one of the most important problems in the world. People have made great efforts by all sorts of ways to protect nature and environment on which they depend for existence.In foreign countries, more than 100 years ago people began setting up national parks, delimiting vast expanses of land. This greatly enlarged the concept of the term "park" and extended it to a wide world of nature. Since then poople have no longer been confined to the gardens or parks in towns or cities but have gone into nature more, loved nature more and protected nature more. The creation of national parks have not only protected nature but have also combined the protection of nature with the protection of historical sites, sightseeing tourism, recreation, sports, scientific research and science popularization and have made all this develop, bringing about very fruitful results.
